    hitachi 42hdx99 powers off and on automatically

    Hi.

    I wonder if someone could tell me what's wrong with this tv. It keeps turning itself, then on again after 8 blinks, then repeats the cycle even after leaving it unplugged for a couple of days. I have attached the photos. Thanks.

    I dont work on plasma's but this sounds like a power supply problem to me. Post closer views of the power supply board (front and back) and I'm sure someone will help you out.

      Odds are it's trying to tell you it has a problem. The service manual might have the information on what 8 blinks mean.

        the pictures are pretty low-res, but from the looks of it, your Y-buffers appear to be integrated into the panel ribbons?? if thats the case, and one of those goes bad, the whole panel is toast.
